Chapter 2: Overview
2. Overview
2.1 Introduction
The DVI-D Matrix Switch is a pure digital crosspoint switch for digital DVI video signals. It simultaneously connects up to eight DVI
sources to up to eight display devices. For each video source, you can either use a “point-to-point” mode (where you connect
exactly one source to exactly one display device), or a “point-to-multipoint” configuration, where the video signal of one input is
distributed to several display devices.
Four models are available:
• 4 x 4 DVI-D Matrix Switch (XPT-DVI4X4)
• 4 x 8 DVI-D Matrix Switch (XPT-DVI4X8)
• 8 x 4 DVI-D Matrix Switch (XPT-DVI8X4)
• 8 x 8 DVI-D Matrix Switch (XPT-DVI8X8)
You can operate the Matrix Switch in four ways:
1. manually using the front-panel switches (buttons)
2. remotely using RS-232 control
3. remotely using the built-in Web server (and your preferred Internet browser)
4. remotely using a Telnet console
The Matrix Switch has a blue LED display on the front faceplate. It normally shows the actual switching state (the current connec-
tions between the inputs and outputs). When operated remotely using the Web interface, the current switching state of the
matrix displays graphically. With console control (RS-232 or Telnet), you can query the switching state using a command language.
When changing DVI connections between video sources and display devices, not only must you switch the video connections/
information, but you must also properly handle the EDID information (which is mandatory in the DVI standards). The Matrix
Switch manages this automatically, according to your setup configuration.
2.2 What‘s Included

DVI-D Matrix Switches
3. Setup and Cabling
3.1 Operation Location Requirements
The Matrix Switch has 40° Ingress Protection (IP) against dust and humidity.
Choose a mounting or operation location where no danger of fluids entering exists. Make sure that the environment falls within
the specified temperature and humidity ranges (see Chapter 1: Specifications for details).
3.2 Setup and Mounting
You can operate the Matrix Switch on a shelf or tabletop. Attach the four rubber feet (included) to each corner on the bottom of
the unit.
Or, you can mount the Matrix Switch in a 19-inch rack, using the brackets supplied. Bracket-mounting is simple. The only tool you
need is a screwdriver (Phillips size 2). Follow these steps:
1. Start on the left-hand side of the unit (the front is the side with the buttons) and unscrew the two front and the two middle
screws completely. Take the bracket that has a center cutout and attach it to the left-hand side of switch, using the longer
M4x5 mm screws contained in the bracket’s bag. Make sure that the switch chassis’ ventilation cutout is not blocked signifi-
cantly by the newly attached bracket.
2. Repeat Step 1 on the right-hand side, using the remaining bracket.
NOTE: When installing the switch on a desktop or in a rack, make sure that nothing will cover the ventilation cutouts on the left-
hand side of the unit.
3.3 Electrical Connections
3.3.1 Connecting the Power
1. Attach the power supply cord to the switch’s IEC-320 connector, which is located on the back of the unit. Now plug the power
plug into a wall outlet.
2. The Matrix Switch has no main power switch, so it will immediately start operation after attaching the unit to a powered wall
outlet.
3. After 10 to 15 seconds, the switch will boot and be ready for operation.
4. The power button’s blue LED should be permanently on when the switch is powered on and active. If the main power fails and
then returns, the switch will return to the active state.
5. To turn off the Matrix Switch, unplug the power cable from the outlet.
CAUTION: Never expose any cables to mechanical stress such as bending or pulling. This can damage cables and impact security.
3.3.2 Attaching DVI Video Sources
The next step in setup procedure is attaching video sources.
1. To avoid damaging your Matrix Switch and your existing video sources, power off ALL units before connecting any compo-
nents. Power off all video sources, too.
2. Connect your DVI video sources to the Matrix Switch, using your DVI-D-video cables (part number EVNDVI02, not included),
one after another. All Matrix Switch inputs of XPT-DVInxn will be labeled with “Input 1” to “Input 8.” You can use any input
you want for a specific source: all inputs are electrically identical.
3. Make a note of all input connections, so that you know which source goes to which input number.
4. You can use any DVI-D cable. However, with high-quality cable you can place your video source up to 112 feet (35 m) away
from the Matrix Switch. Each input has a signal equalizer that refreshes the signal to standard levels.

724-746-5500 | blackbox.com
Page 11
Chapter 3: Setup and Cabling
NOTE: If you have the XPT-DVI4X4 or XPT-DVI4X8, the inputs labeled “Input 5” to “Input 8” are not used. You can’t route signals
from these inputs to any output. Your equipment will not be damaged if you attach video sources to these inputs by
accident.
5. Install and tighten the screws on the male DVI connector.
3.3.3 Attaching DVI Display Devices
1. Connect your display devices (for example, monitors, LCDs, or beamers) to the outputs of the Matrix Switch, using your DVI-D
cables (not included, part number EVNDVI02). All outputs of the unit are labeled “Output 1” to “Output 8.” Use any of the
available outputs for your devices: all outputs are electrically identical.
NOTE: If you have the XPT-DVI4X4 or XPT-DVI8X4, the outputs labeled “Output 5” to “Output 8” are not used. You can’t route
signals from these inputs to any output. Your equipment will not be damaged if you attach video sources to these outputs
by accident.
2. Write down which output goes to which of your display devices, so you have a record of the configuration.
NOTE: Do not use DVI cables longer than 16 feet (5 m) as output cables when using maximum video resolutions such as 1600 x
1200 pixels.
3. Install and tighten the screws on the male DVI connector.
3.3.4 RS-232 Connection
If you intend to control the XPT-DVInxn matrix switch by a PC or laptop using the RS-232 serial interface, connect the included
serial cable to the DB9 F connector on the back of switch labeled RS-232. Connect the other end of the cable to the serial inter-
face of your PC/Laptop’s serial interface (console) port. If your equipment does not have a serial interface or connector, you can
control the switch by network/TCP or using a USB/RS-232 converter dongle (part number IC834A or equivalent). Connector pin-
nings and serial interface configuration data are described in Chapter 1: Specifications.
3.3.5 TCP/IP Connection
Using a TCP/IP network connection, you can control the Matrix Switch remotely using either a Web interface or a Telnet console
session. If you want to use this kind of control, connect a standard network cable (100-Mbps CAT5 or higher) to the port labeled
“TCP/IP” on the back of the switch. The switch will support 10- and 100-Mbps TCP/IP networks but does not have an Auto
MDI-X mode. You either need to use a crossover-pinned cable or your PC’s network adapter must conform to the Auto MDI/
MDI-X standard so that you can use a straight-pinned cable.

Chapter 4: Operation
4. Operation
4.1 Powering On/Off; Standby Operation
When the DVI-D Matrix Switch is connected to a powered wall socket, it will start and boot automatically. All button LEDs will
flash for a short period of time and the text display will show a short welcome message (from the bootloader). After that, the unit
tries to reach a TCP/IP network (if cable is connected).
After 10 seconds at most, the unit is up and ready for operation. The text display will switch to a “status display” mode (see
Figure 4-1). You can read all active routing connections from that status display. All available outputs are written in the top row,
starting with “OUT.” The lower row displays the number of the input connected to the output above. A minus sign means that
the output has NO connection to any input.
OUT: 1 2 3 4 5 6 7 8
IN: - 6 4 - 5 - 3 1
Figure 4-1. Routing status display (example).
The example in Figure 4-1 reads:
• Outputs # 1, 4, and 6 are off
• Output #2 shows video connected to input #6
• Output #3 shows video connected to input #4
• Output #5 shows video connected to input #5
• Output #7 shows video connected to input #3
• Output #8 shows video connected to input #1
If you press the “O/I” button on the front panel for longer than three seconds, the DVI-D Matrix Switch will quit active mode and
go to standby mode. All active connections break, and the unit will turn off most of its internal functions.
If the unit is in standby, you can activate it by pressing the “O/I” button longer than about one second. Then, all previous routing
connections are re-established (both video and EDID connections).
4.2 Operation Outline
You can operate the Matrix Switch by different methods. These methods differ in complexity and level of control, so both new
and advanced users will find their appropriate control method.
The next sections explain how to:
• make and break video routing connections
• save and recall setup scenarios with “presets”
• control the system’s menu tree
• control the system’s features through remote interfaces such as a console or a Web interface
4.3 Setting Up Video Connections between Inputs and Outputs
4.3.1 Making a Connection
First, select the output number of the connection you intend to make by pressing one of buttons “1” to “8” for the XPT-DVI4X8
or XPT-DVI8X8 (“1“ to “4“ for the XPT-DVI4X4 or XPT-DVI8X4). The selected output’s LED will flash slowly. The cursor in the text
display will flash the number of the selected output channel.

724-746-5500 | blackbox.com
Page 14
DVI-D Matrix Switches
Press one of buttons “1” to “8” for the XPT-DVI8X4 or XPT-DVI8X8 (“1” to “4” for the XPT-DVI4X4 or XPT-DVI4X8) to connect
to the selected input number. The former flashing LED will go blank, and the status text display will show the newly established
connection.
4.3.2 Modifying or Breaking an Existing Connection
You can modify an existing connection by re-establisting a new connection/routing, as described in Section 4.3.1. To break an
existing connection, press the number of the output you want to turn off (break connection). When the LED light flashes, press
the “P” button. This will break the connection and turn off the LED. The text display will show a minus sign under the selected
output number, indicating that the connection is off.
4.4 Saving and Recalling Presets
You can save or recall a routing setup any time you want. By saving a preset, you can preserve a complex setup for later use. By
recalling a setup, you can switch several channels synchronously.
4.4.1 Saving a Preset
To preserve the routing state of DVI-D Matrix Switch, that is, which inputs are connected to which outputs, the switch offers
eight so-called “presets.” These presets are non-volatile, that is, even after power loss you can restore your system routing if you
have saved it to a preset bank before.
To save a setup as preset, make all connections you want. Then press the “P” button longer than a second. The text display then
switches to the “PRE-SAVE” mode, as shown in in Figure 4-2.
PRE: 1 2 3 4 5 6 7 8
SAVE: F- FF- F- -
Figure 4-2. Saving a preset.
The display now shows eight available preset banks (storage locations) in the top row, the lower row shows the usage status of
the bank. A caret symbol means that the preset bank is already used, but can be overwritten. A minus sign means, the preset
bank is free.
To select a preset bank, move the cursor to the numbered location and press the appropriate numeric LED button. After you
select a preset bank, the text display will return to the status display shown in Figure 4-1 and all LEDs will stop flashing.
If you don’t want to save this preset, press the “P” button instead of one of the numeric buttons. The preset save dialog will be
canceled and text display will return to standard status display shown in Figure 4-1.
NOTE: Only the actual routing information will be stored into a preset bank. No EDID content will be saved (and recalled later)
using the preset functions.
4.4.2 Recalling a Preset Setup
To load (recall) a saved preset, press the “P“ button. The text display will switch to a “PRELOAD” mode, as shown in FIgure 4-3.
PRE: 1 2 3 4 5 6 7 8
LOAD: F- FF- F- -
Figure 4-3. Loading a preset.
The top row will display all eight preset banks, the lower row will show all used banks with carets and all unused free banks are
as minus signs.

724-746-5500 | blackbox.com
Page 15
Chapter 4: Operation
The numeric buttons’ integral LEDs that correspond to the used banks will flash slowly, indicating that you can recall them. To
choose the preset number you want, press the numeric button on the front panel. The preset immediately loads, that is, the video
routing is modified immediately according to the saved routing configurations. After loading, the text display will return to the sta-
tus display mode shown in Figure 4-1. To cancel the recall process, press the “P” button instead of one of the numeric buttons,
and the text display will return to a standard status display and the LEDs will stop flashing.
4.5 Menu Functions
4.5.1 Menu System
Using the built-in menu system, more complex system functions are available. To handle the menu system, you have to use the
four cursor buttons (arrows up, down, left, right) and the “enter” button, located to the right of the “right” cursor button. With
these buttons, you can navigate through a menu tree to access more complex system functions.
To operate the menu, these rules apply:
• When the text display shows the standard status information as shown in Figure 4-1, press the “right,” “up,” “down,” or
“enter” button to open the menu.

4.6 Console and Telnet Access
4.6.1 Introduction to Console/Telnet
Console and Telnet connections to the unit are different in terms of electrical connectivity, but both access methods share the
same command set and handling.
For serial remote control, use the serial cable shipped with the unit. Connect the cable to any available serial port (for example,
COM1) of your PC/Laptop. At the unit, attach the serial cable to the DB9 connector labeled RS-232 on the back of the unit.
The serial interface parameters are 57600 8N1, which are described below:
• baud rate: 57.6 kbps
• data bits: 8
• stop bits: 1
• parity: None
You can use HyperTerminal, which is included with Microsoft Windows®operating systems, or any other terminal application
programs available on your operating system.
For a Telnet connection, attach the unit to your local network (LAN) via an STP/UTP cable (not included). At the unit, use the rear
connector labeled “TCP/IP.” Any TCP/IP network with 10 or 100 Mbps is supported. To adjust network parameters, use the menu
buttons/front panel as described in Section 4.5. Or, use a serial console connection (and commands described next) to adjust net-
work parameters.
If your LAN supports DHCP, then the unit will be assigned automatically and you can simply read the IP address assigned via the
front-panel menus (Status/Network Status/IP).
To control unit via Telnet, use a special Telnet application like “PUTTY“ or use the Windows®command line “telnet aaa.bbb.ccc.
ddd“ while using the unit’s IP adress as aaa.bbb.ccc.ddd in dotted numerical format, i.e. “telnet 192.168.0.100“.
Both access methods (serial or Telnet) will open a console application, where you can type in commands and receive replies.
First of all, you have to authenticate to the unit, because configuration access is password protected to avoid unauthorized use of
the unit. With the factory setting defaults, login is possible using:
Login: any
Password: any
NOTE: These are case sensitive. Any command line ends by typing the “Enter” key on your keyboard.
Here are some hints for console control:
• you can add additional users using the „sys_addusr“ command (see below)
• you can get a list of all commands available by typing „help“ or „?“
• a short help message to any command is available by typing „? <command>“ where <command> is the command string you’re
interested in. Don’t forget the space in between the question mark and the command.
• Issuing “exit“ command will log off the serial console (you have to re-login) respectively will close the Telnet session.

4.6.2 Console Command Descriptions
edid_clear
Format: edid_clear N
Clears the content of EDID bank #N. All EDID information stored is discarded.
CAUTION: There is no request dialog; the command is executed immediately.
edid_list
Format: edid_list
Lists the EDID banks’ usage status. If a bank contains no EDID information, the status is “empty.“ If a bank is used, the EDID
monitor name (if available) of the bank content is displayed. If there is no name in the EDID data but there is valid EDID data
(checksum is OK), just “valid“ is displayed as the bank’s status.
Using the unit’s Web interface you can even assign a name of the bank, but this is not available via console or Telnet.
edid_mode
Format 1: edid_mode
Displays the behavior of EDID/DDC for each input. This is a typical printout (factory setup):
IN: 1 2 3 4 5 6 7 8
DDCM: S S S S S S S S
When reading the example, the first row will list all inputs available at the unit and the second row will show a character
abbreviation for the input number in the row above.
All eight inputs (of the example) are configured to “S” (=STATIC).
Use Table 4-1 to interpret the abbreviations used.
Table 4-1. Abbreviations for EDID mode.
Character EDID mode
- OFF: no EDID available at input, hot-plug is off. An external video source will not read any EDID
info, as long as the unit is powered. When power is off, any input of the unit will behave like
“static“ (see below) to be DVI compliant.
S STATIC: a static EDID data set is presented at the input. The hot-plug signal is always ON. A
video source is able to read EDID/DDC data at any time.
F FOLLOW: see Section 5.2.2
T THROUGH: see Section 5.2.3
Format 2: edid_mode in mode
Parameter: in = [1..input count available]: number of input used
mode = mode character (see Table 4-1)
Modify the EDID operation mode of input number #in. The command is executed directly. The new EDID behavior mode is
stored, so even after the power is reset, the input will behave the same way.
edid_read
Format 1: edid_read N

724-746-5500 | blackbox.com
Page 19
Chapter 4: Operation
Parameter:
N = [1..input count] read back EDID to console from output #N
N = [11..(10+input count)] read back EDID from input EEPROM of input #(N-10)
N = [21..28] read back EDID from internal bank manager bank # (N-20)
This command displays EDID information. These infos (read back) will be printed onto the console.
This is a typical printout:
>edid_read 11
Reading internal DDC from input #1

EDID is valid!
EDID monitor name: 'CROSSBAR 8'
All data is printed in hexadecimal format. If available, the EDID monitor string is printed, too. The message “EDID is valid!” means
that EDID checksum is OK and EDID is valid.
Format 2: edid_read N M
Parameter:
N = [1..output count]
M = [1..8]
Reads back EDID data from output #N and saves this data to internal bank manager bank #M if readback data is valid (checksum
is OK).
CAUTION: If bank #M is already used, the new data will overwrite the old information with the user request.
edid_write
Format: edid_write N M
Parameter:
N = [0, 1..8]
M =[1..input count]
Copies EDID data from bank manager’s bank #N to input #M’s EDID EEPROM. If bank #N is empty, an error message is displayed.
If using N=0, the unit will use factory EDID. Using this systax will reset input #M to the factory setting. The input EEPROM #M is
overwritten immediately, independent of the EDID mode (-, S, F, T) of the input #M. When EDID mode is “follow” (F), the input
EEPROM is overwritten again after the next routing change that concerns input #M.

The preferred application of this command is using it with inputs in “static“ (S) EDID mode. If your video source is not sourcing
video data because it does not like the “factory” EDID info of the input, you can read back EDID data of a displaying device
(important: that is WORKING with the source) from the output and store it on a bank manager’s bank available, using the “edid_
read” command. Then, copy the bank content to the input where your source is attached (using “edid_write”) and then make
sure the desired input is in static mode. Your video source will get exacly the same EDID information as when connected to the
display directly.
exit
Format: exit
Quits the console application. For a serial console, the user is logged off. For a Telnet terminal session, the session is closed. To
reconnect, you have to start a new Telnet session again.
gettime
Format: gettime
Displays the system’s clock time.
help
Format 1: help
Lists all commands available.
Format 2: help <command>
Displays additional help text for command <command>.
ifstat
Format: ifstat
Displays network connectivity status of TCP/IP network interface.
Example:
>ifstat
IF IP addr Def Gtway state type H/W addr
0 10.0.1.61 10.0.1.2 UP Ethernet 0 :60:35:6 :26:29
Table 4-2. ifstat’s parameters and their interpretations.
Parameter Interpretation
IF number of network interface. Reads always ”0“ with this unit.
IP addr actual IP adress of the unit.
Def Gtway default gateway’s IP adress
state internal (to the unit) network interface status. “UP” does not mean that a nework LINK is UP, just that
the internal network components are up.
type reads always “Ethernet“
H/W addr the network interface”s MAC address.
ReadOnly, because this is used as system identification.
Use this MAC address if you want to assign a static IP adress to the unit using a DHCP server
(static DHCP). Ask your network administrator for more information.
